# List of inventoried conifers in Canada

Canada's national forest inventory includes many native conifer species. All except the larches are evergreens. Most are in the pine family, except for yews (in the yew family) and junipers, Alaska cedars and thuja cedars (in the cypress family).
Softwood from North American conifers has a variety of commercial uses. The sturdier timber is milled for plywood, wood veneer and construction framing, including structural support beams and studs. Logs can be fashioned into posts, poles and railroad ties. Less sturdy timber is often ground and processed into pulpwood, principally for papermaking. Resins from sap yield wood tar, turpentine or other terpenes. Some resins and other tree products contain dangerous toxins (not generally listed below).
